In the clip, via TVLine, Barry and Iris are required to flash into S.T.A.R. Labs after a Level 11 emergency is accidentally activated.

Since the newlyweds are on their honeymoon and no one else is in the lab, Ralph (Hartley Sawyer) decides to take advantage and watch some Netflix, but triggers an alarm instead. As you can imagine, Iris is less than thrilled to have to come back for something not so emergency-related.

“Do you know how hard it is to run in flip flops?” Barry says at the end of the clip. LOL!
